Second Amendment to Credit and Guaranty Agreement

On October 20, 2010, Boise Inc.’s indirect wholly owned subsidiary, Boise Paper Holdings, L.L.C. (“Holdings”), BZ Intermediate Holdings LLC and subsidiaries of Holdings, as guarantors, various lender parties, and Goldman Sachs Credit Partners L.P., as administrative agent, entered into a Second Amendment to Credit and Guaranty Agreement, which amends various terms in our Credit and Guaranty Agreement dated as of February 22, 2008 (“Credit Agreement Amendments”). The Credit Agreement Amendments allow us to make various types of restricted payments, including the payment of dividends, the repurchase of our stock and warrants, and the repayment or repurchase of our senior notes. These restricted payments are limited to a “permitted restricted payment amount,” which is calculated as the sum of 50% of “net income for distributions,” together with other amounts, all as described in the Credit Agreement Amendments. In addition, the Credit Agreement Amendments eliminate any ongoing requirement that we use our excess cash flow to repay debt.

The above summary does not purport to be complete and is subject to and qualified in its entirety by reference to the text of the Second Amendment to Credit and Guaranty Agreement filed as Exhibit 99.1 to this Current Report on Form 8-K. Exhibit 99.1 is incorporated by reference into this Item 1.01.
